I know Kats are notoriously cold blooded and can be a bit tempermental after sitting for awhile. If im out riding, its perfect, never gives me a bit of trouble..If I stop for gas, or a pack of smokes, or even at a restaurant, she fires right back up, no problems. But after sitting for several hours or overnight, especially when its colder out in the morning, it takes quite a while to get her started, like atleast a good 15 cranks of the starter. Im thinking it could be faulty plugs, but they were supposed to have been changed when i bought the bike about 4 months ago or so, although I havent verified that..but they could be bad or just cheap, maybe not gapped right? Or could it be something in the fuel lines? I've tried leaving it on prime for like 30 seconds, and then start, still the same..tried to choke, still the same. I can see the choke cable move when I engage it, so as far as I can tell, its not a faulty cable or improperly hooked up.

Any suggestions?

Not sure on that one. I can tell you my carbeurated SV needs more and more choke over time, particularly in the cooler mornings. When I leave from work in the afternoon, she starts right up.

Plugs might be a good place to start, but don't you have to take off a lot of bodywork? :eek:

Had the same problem at the beginning of the season. I changed the plugs and it's been good every since. Whille your there might as well clean or get a new airfilter. Oh, and a good tip, make sure your tank is empty or almost empty. I filled up not thinking of what I had to do and it was a pain in the arse. I also have the shop manuel for our bikes so any thing you need me to look up just let me know.

im leaning towards the plugs as well..since winter is coming up, I can hang tight till then and just replace them b/4 spring. but yeah keep that manual handy jdog.

Possibly. But if it is happening everytime after sitting for a period of time, I would lean more towards the plugs. Not excessive gas.

Well, I'll jump on the band wagon of plugs too. What the heck! When it comes to replacing them, go with NOTHING but NGK!!!!!!! They make about the best plug out! I put in a set of iridium NGK's this spring and they rock!

Also, something that you may want to consider is getting the bike re-jetted. I'm not saying for a large performence gain but it usually helps. On both bikes I've had re-jetted, including my 9, I can if I want start it up during the summer w/o choke. Even when the motor is dead cold! I runs low but will start up with little effort!

However, Shan is also onto something. Make sure your choke is ajusted properly. It is like any other cable and can stretch out. You may have alot of slack in it and that may be a cause. On the other hand, I think this is far fetched. It really isn't used that much compared to your clutch cable or throttle. So I'd say new plugs and think about even a factory re-jet!

My Yam will not start under 50 degrees. Other than that it is usually good unless I leave it sit for too long as I think my battery is about toast. Did the person before you winterize the bike properly? Plugs are notorious for going bad on bikes over winter, etc. with the tarnished fuel, etc. The rejetting can't hurt either.

approximate cost of rejetting ? dont know how it was winterized,but it was a local 1 owner, and maintenance was kept up at the same dealer I bought it from.

It varies and most dealerships won't do it because it's against those crappy EPA rules...

I can't remember what I paid, maybe like $100-150 for the jet kit and $125 for install by a guy that runs a private shop! Maybe...I'd have to look it up!

Damn, every once and a while my memory serves me well.

I paid $120 for the stage 2 jet kit from Muzzy (cause I own a Kaw) and $150 for the install. Which include a sync of my carbs.

That could also be one of the problems. Your carbs just may need to be cleaned and syncd! You can get that done at most dealerships or shops. It will be cheaper to take the carbs off and take just them in instead of the entire bike but either way! That might be another suggestion to consider. Of, coarse you could go my way and do both!!

so the carb problem would be more evident after sitting for awhile, as opposed to when the engine is nice and warm from riding?
